In a general way, it may be pointed out, the sources of demand for exchange conform with influences which cause exchange to go up, and the sources of supply of exchange constitute causes which make for low rates. It is to be noted, however, that money rates are a great factor influencing foreign exchange. Whenever money is cheap at any given centre, and borrowers are bidding only low rates for its use, lenders seek a more profitable field for the employment of their capital. Money rates in the New York market are not often less attractive than those in London, so that American floating capital is not generally employed in the English market, but it does occasionally come about that rates become abnormally low here and that bankers send away their balances to be loaned out at other points. Such a time was the long period of stagnant money conditions following the 1907 panic. Trust companies and banks who were paying interest on large deposits at that time sent very large amounts of money to the other side and kept big balances running with their correspondents at such points as Amsterdam, Copenhagen, St. Petersburg, etc.--anywhere, in fact, where some little demand for money actually existed. Demand for exchange with which to send this money abroad was a big factor in keeping exchange rates at their high level during all that long period. High money rates at some given foreign point as a factor in elevating exchange rates on that point might almost be considered as a corollary of low money here, but special considerations often govern such a condition and make it worth while to note its effect. Suppose, for instance, that at a time when money market conditions all over the world are about normal, rates, for any given reason, begin to rise at some point, say London. Instantly a flow of capital begins in that direction. In New York, Paris, Berlin, and other centres it is realized that London is bidding better rates for money than are obtainable locally, and bankers forthwith make preparations to increase the sterling balances they are employing in London. Exchange on that particular point being in such demand, rates begin to rise, and continue to rise, according to the urgency of the demand. The international money markets are a most decidedly complex proposition, and there is literally never a time when several influences tending to put exchange rates up are not conflicting with several influences tending to put rates down. The actual movement of the rate represents the relative strength of the two sets of influences. To be able to "size up" the influences present and to gauge what movement of rates they will result in, is an operation requiring, first, knowledge, then judgment. The former qualification can perhaps be derived, in small degree, from study of the foregoing pages. The latter is a matter of mental calibre and experience.
